Description

Technical Field

[0001] This utility model relates to the field of intelligent waste sorting, and more specifically, to a sorting device. Background Technology

[0002] With the development of the times, people's awareness of environmental protection has been continuously strengthened, and garbage classification policies have been gradually promoted in major cities. However, traditional garbage classification mainly relies on manual sorting, which is not only inefficient, but also has certain negative effects on human health if such work is carried out for a long time.

[0003] Currently, there are some waste sorting equipment on the market. Some use a single conveyor belt to transport waste and then sort it into the corresponding waste bins after visual recognition, while others use mechanical grippers to visually recognize the waste poured into the device before sorting and picking it up and placing it into the corresponding waste bins.

[0004] However, during the disposal process, different types of garbage may pile up together, causing the camera to perform incorrect image recognition, resulting in incorrect garbage sorting. Existing technology discloses a garbage processing device, mainly including a mounting bracket, a bidirectional conveyor (first and second), a high-definition camera, a feeder, multiple garbage bins, a lower-level machine, and a microcomputer. It uses two transmission belts with a 135° angle to convey garbage in opposite directions, effectively "rubbing" the garbage to separate piled-up garbage, facilitating subsequent garbage sorting, identification, and processing.

[0005] However, the existing technology has at least the following problems: when two or more pieces of garbage lean against the same side of the conveyor belt at the same time, the overlapping garbage is only subjected to the force of the conveyor belt on one side. The overlapping garbage will move in the same direction, which will cause the garbage to not be "rubbed" apart well. The success rate of separation is not high enough, which will cause the camera to make incorrect image recognition and reduce the accuracy of garbage classification. Utility Model Content

[0006] The purpose of this invention is to overcome the problem that the success rate of separating stacked garbage in existing garbage sorting equipment is not high enough, and to provide a sorting device that improves the success rate of separating stacked garbage, thereby improving the accuracy of garbage classification.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A sorting device is provided, comprising a frame, a separation device, a feeding conveyor, a camera, a dispensing device, and at least two trash cans located within the frame. The top of the frame has a feed inlet, the separation device is located below the feed inlet, and the feed end of the feeding conveyor is located below the discharge end of the separation device. The camera is used to identify the type of trash on the feeding conveyor, and the dispensing device is used to dispose of the identified trash into the corresponding trash can. The separation device includes a first conveying mechanism, a second conveying mechanism, and a diversion mechanism, each mounted on the frame. A V-shaped cavity is formed between the conveying surfaces of the first and second conveying mechanisms. The diversion mechanism is located between the first and second conveying mechanisms and has at least two protrusions, with a diversion port formed between adjacent protrusions.

[0009] This utility model discloses a sorting device where unsorted waste is fed into a separation unit through an inlet. The separation unit includes a diversion mechanism. When two or more pieces of waste stacked together fall into the inlet, they are likely to be separated into two sides of the diversion mechanism. Each piece of waste is supported by a conveyor mechanism, thus completing the separation. If two pieces of waste stacked together fall into the same side of the diversion mechanism simultaneously, the stacked waste will be propelled forward by one of the conveyor mechanisms until it passes through the diversion port. At this point, one side of each piece of waste is in contact with one of the conveyor mechanisms, and the other side is in contact with the stacked waste. Each side of the two pieces of waste is subjected to frictional forces from the two conveyor mechanisms. The contact point between the two pieces of waste is close to a protrusion. Under the obstruction and guidance of the conveyor, the protrusions provide two obstructing forces on the garbage. As the other side of the garbage is driven forward by the conveyor mechanism, this forces the garbage to change its position towards one side of the conveyor mechanism. This causes the two overlapping garbage items to be separated to the two sides of the diversion mechanism. Each piece of garbage leans against one side of the conveyor mechanism, thus completing the separation of garbage. Even when overlapping garbage leans against the same side of the conveyor mechanism, it can still be separated by the diversion mechanism, improving the success rate of garbage separation and ensuring the accuracy of subsequent image detection. After leaving the separation device, the garbage falls into the feeding conveyor. The camera will identify the type of garbage on the feeding conveyor. The disposal device will transfer the garbage to the corresponding garbage bin according to the signal sent by the camera, thus completing the garbage sorting.

[0010] Furthermore, the protrusion is a triangular prism with any one edge facing the top surface of the frame, and the end of the protrusion away from the discharge end of the separation device has a beveled portion. The beveled portion changes the angle of the contact surface between the waste and the protrusion, reducing the possibility of waste getting stuck in the diversion port.

[0011] Furthermore, the conveying directions of both the first and second conveying mechanisms are parallel to the horizontal plane, and the conveying speed of the first conveying mechanism differs from that of the second conveying mechanism. When two overlapping pieces of waste pass through the diversion port, they are separated on either side of the diversion mechanism and are driven forward by conveyor belts located on either side of the diversion mechanism. Because the conveying speeds of the first and second conveyor belts are different, the distance between the two pieces of waste can be increased, improving the accuracy of subsequent image recognition.

[0012] Furthermore, the feeding and conveying device is a belt conveyor mechanism, and the conveying direction of the feeding and conveying device is parallel to the horizontal plane and perpendicular to the conveying direction of the first conveying mechanism. When the garbage leaves the separation device, it will fall onto the feeding and conveying device below. The feeding and conveying device will move the garbage horizontally. During this process, the image is captured and recognized by the camera. The entire conveying process is smooth. After being separated by the separation device, the piled garbage will move forward at different speeds, and the time it takes to fall from the separation device into the feeding and conveying device will also be different. The position of the garbage falling onto the feeding and conveying device will also be different, which improves the accuracy of detection.

[0013] Furthermore, a first baffle is provided on the side of the feeding and conveying device away from the separating device. Since the waste undergoes a projectile motion on its way from the separating device to the feeding and conveying device, the first baffle can block the waste and prevent it from leaving the feeding and conveying device due to excessive speed.

[0014] Furthermore, the disposal device includes a first driving component and a supporting component. The first driving component drives the supporting component to move onto the trash can. The supporting component includes a second driving component, a supporting member, and a second baffle. The second driving component is connected to the second baffle, and the supporting member is connected to the output end of the second driving component. The second baffle blocks the trash and causes it to fall into the trash can. The supporting component is designed to catch the trash and, driven by the first driving component, reach the corresponding trash can. The movement of the supporting member itself causes the trash to be blocked by the second baffle and fall into the trash can. This method of positioning before disposal provides better accuracy.

[0015] Furthermore, the frame is provided with a fixed shaft, and the trash can is arranged circumferentially along the fixed shaft. The first drive assembly includes a first drive member mounted on the frame, a first gear mounted on the output end of the first drive member, and a gear disk meshing with the first gear. The second drive assembly includes a second drive member mounted on the second baffle, a second gear mounted on the output end of the second drive member, and an internal rack fixed to the support member and meshing with the second gear. The second baffle is fixedly connected to the gear disk. The gear disk, the second baffle, and the support member are all rotatably connected to the fixed shaft. The support member is located between the second baffle and the gear disk. After the garbage leaves the feeding and conveying device, it falls onto the support. Then, the first drive unit drives the first gear to rotate, which in turn drives the gear disk meshing with the first gear to rotate. Since the second baffle is fixedly connected to the gear disk, the second drive unit mounted on the second baffle is in a self-locking state. The second drive unit meshes with the internal rack fixed on the support. Therefore, the rotation of the gear disk will drive the second baffle and the support to rotate together. When the whole rotation reaches the position of the corresponding garbage bin, the first drive unit stops running and is in a self-locking state. The gear disk and the second baffle are both in a fixed state. Then, the first drive unit starts, driving the support to rotate around the fixed axis. The garbage on the support will be obstructed by the second baffle until it leaves the support and falls into the garbage bin. Then, the second drive unit starts, driving the support to reset. Then, the first drive unit starts, driving the whole unit back to the discharge end of the feeding and conveying device. The disposal device can dispose of garbage into the corresponding garbage bin according to the information fed back by the camera. It adopts a wheel-type design with a short movement stroke, which improves the sorting speed.

[0016] Furthermore, a post is provided at the bottom of the second baffle, and a slot is provided on the gear disk, with the post inserted into the slot. The insertion of the post into the slot secures the second baffle and the gear disk. The fit between the post and the slot facilitates easy assembly and disassembly, and reduces the need for future maintenance.

[0017] Furthermore, it also includes a third baffle connected to the second baffle, with the second and third baffles located on opposite sides of the support member in the circumferential direction. When waste falls from the feeding conveyor onto the support member, the second and third baffles respectively block the sides of the support member, preventing waste from falling from the sides.

[0018] Furthermore, the device also includes a compression mechanism. A compression groove is provided on the side of the trash can. The compression mechanism includes a third drive unit fixed to the frame and a compression plate connected to the output end of the third drive unit. The compression plate is slidably connected to the compression groove. The third drive unit drives the compression plate to slide within the compression groove, compressing the trash inside the trash can and increasing its storage capacity.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The diversion mechanism is designed so that even when overlapping waste leans against the conveyor on the same side, the overlapping waste will enter the diversion port. Under the obstruction and guidance of the protrusion, the two overlapping pieces of waste will be separated to the two sides of the diversion mechanism, which improves the success rate of waste separation and ensures the accuracy of subsequent image detection.

[0021] 2. The conveying speed of the first conveying mechanism is different from that of the second conveying mechanism, which can increase the distance between the two pieces of waste and improve the accuracy of subsequent image recognition;

[0022] 3. The dispensing device adopts a disc-type design, which has a short travel distance and improves the sorting speed;

[0023] 4. The compression device can compress the garbage that needs to be compressed, increasing the storage capacity of the garbage can. Attached Figure Description

[0033] Example 1

[0034] A sorting device, such as Figure 1 and Figure 2As shown, the system includes a frame 100, a separation device 200, a feeding conveyor 300, a camera 400, a dispensing device 500, and four garbage bins 700 located within the frame 100. The four garbage bins 700 are designated as food waste bins, hazardous waste bins, recyclable waste bins, and other waste bins, respectively. A rectangular inlet 110 is located at the top of the frame 100. The separation device 200 is located below the inlet 110, and the feed end of the feeding conveyor 300 is located below the discharge end of the separation device 200. The camera 400 is used to identify the type of waste on the feeding conveyor 300. The dispensing device 500 is used to dispose of the identified waste into the corresponding garbage bin 700. In this embodiment, the dispensing device 500 is a robotic arm. The separation device 200 includes a first conveying mechanism 210, a second conveying mechanism 220, and a diversion mechanism 230, all mounted on the frame 100. In this embodiment... In this design, both the first conveying mechanism 210 and the second conveying mechanism 220 are belt conveying mechanisms, but they can also be chain conveying mechanisms, roller conveying mechanisms, etc. The conveying directions of the first conveying mechanism 210 and the second conveying mechanism 220 are parallel to the horizontal plane. The included angle between the conveying surfaces of the first conveying mechanism 210 and the second conveying mechanism 220 is 135°. A V-shaped cavity is formed between the conveying surfaces of the first conveying mechanism 210 and the second conveying mechanism 220. The diversion mechanism 230 is located between the first conveying mechanism 210 and the second conveying mechanism 220. The diversion mechanism 230 is provided with three protrusions 231. Each protrusion 231 is a triangular prism with any one edge facing the top surface of the frame. One edge of the protrusion 231 is located at the top of the protrusion 231. The end of the protrusion 231 away from the discharge end of the separation device 200 is provided with a beveled part 233. A diversion port 232 is formed between two adjacent protrusions 231.

[0035] The working principle of this embodiment is as follows:

[0036] This utility model discloses a sorting device. Unsorted waste is fed into a separating device 200 through an inlet 110. The separating device 200 is equipped with a diversion mechanism 230. When two or more pieces of waste stacked together fall into the inlet 110, they may be separated into two sides of the diversion mechanism 230. Each piece of waste is supported by a conveying mechanism, thus completing the separation of waste. If two pieces of waste stacked together fall into the same side of the diversion mechanism 230 at the same time, the stacked waste will be driven forward by one of the conveying mechanisms until it passes through the diversion port 232. At this point, one side of each piece of waste is in contact with one of the conveying mechanisms, and the other side is in contact with the waste stacked with it. One side of each piece of waste is subjected to the frictional force of the two conveying mechanisms, and the contact point of the two pieces of waste is close to the protrusion 231. Under the obstruction and guidance of 31, the protrusion 231 will provide an obstructing force on the garbage. As the other side of the garbage is driven forward by the conveying mechanism, this will force the position of the garbage to change towards one side of the conveying mechanism, so that the two overlapping garbage will be separated to both sides of the diversion mechanism 230. Each garbage leans against one side of the conveying mechanism, thus completing the separation of garbage. Even when the overlapping garbage leans against the same side of the conveying mechanism, it can still be separated by the diversion mechanism 230, improving the success rate of garbage separation and ensuring the accuracy of subsequent image detection. After leaving the separation device 200, the garbage falls into the feeding conveying device 300. The camera 400 will identify the type of garbage on the feeding conveying device 300. The robot will transfer the garbage to the corresponding garbage bin 700 according to the signal sent by the camera 400, thus completing the garbage sorting.

[0037] The beneficial effects of this embodiment are as follows:

[0038] The diversion mechanism 230 is designed so that when overlapping waste passes through the diversion port 232, the overlapping waste will enter the diversion port 232. Under the obstruction and guidance of the protrusion 231, the two overlapping pieces of waste will be separated to both sides of the diversion mechanism 230, which improves the success rate of waste separation and ensures the accuracy of subsequent image detection. The setting of the oblique cut 233 changes the angle of the contact surface between the waste and the protrusion 231, reducing the possibility of waste getting stuck in the diversion port 232. The first conveying mechanism 210 and the second conveying mechanism 220 adopt belt drive, which has a large frictional force acting on the waste, ensuring the waste transmission rate.

[0039] Example 2

[0040] This embodiment is a second embodiment of a sorting device. This embodiment is similar to the first embodiment, except that, as shown in the example... Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the frame 100 is provided with a fixed shaft 120, and four trash cans 700 are arranged circumferentially along the fixed shaft 120. The disposal device 500 includes a first drive assembly 510, a second drive assembly 520, a support member 530, a second baffle 540, and a third baffle 550 connected to the second baffle 540. The support member 530 is an arc plate with a circumferential angle of 120°. The first drive assembly 510 includes a first drive member 511 mounted on the frame 100, a first gear 512 mounted on the output end of the first drive member 511, and a gear disk 513 meshing with the first gear 512. The second drive assembly 520 includes a second drive member 521 mounted on the second baffle 540, and a third baffle 550 connected to the second drive assembly 510. The second gear 522 at the output end of component 521 and the internal rack 523 fixed on the support component 530 and meshing with the second gear 522 are included. The second baffle 540 includes a second baffle 540 and a third baffle 550, which are located on both sides of the support component 530 in the circumferential direction. A pin 541 is provided at the bottom of the second baffle 540. A slot 514 is provided on the gear disk 513, and the pin 541 is inserted into the slot 514. The gear disk 513, the second baffle 540 and the support component 530 are all rotatably connected to the fixed shaft 120. The support component 530 is located between the second baffle 540 and the gear disk 513. In this embodiment, the first drive component 511 and the second drive component 521 are both motors.

[0041] The working principle of this embodiment is as follows:

[0042] After the garbage on the feeding conveyor 300 leaves the feeding conveyor 300, it falls onto the support member 530. Then, the first drive member 511 drives the first gear 512 to rotate clockwise, thereby driving the gear disk 513 meshing with the first gear 512 to rotate counterclockwise. Since the second baffle 540 is fixedly connected to the gear disk 513, the second drive member 521 installed on the second baffle 540 is in a self-locking state at this time. The second drive member 521 meshes with the internal rack 523 fixed on the support member 530. Therefore, the rotation of the gear disk 513 will drive the second baffle 540 and the support member 530 to rotate counterclockwise together. When the whole thing rotates to the corresponding garbage bin 7 After reaching position 00, the first drive component 511 stops operating and enters a self-locking state. The gear disk 513 and the second baffle 540 are both in a fixed state. Then, the second drive component 521 starts, driving the support component 530 to rotate clockwise around the fixed shaft 120. In this embodiment, the garbage on the support component 530 will be obstructed by the second baffle 540 until it leaves the support component 530 and falls into the garbage bin 700. Subsequently, the second drive component 521 reverses, and the first drive component 511 also starts at the same time. The second drive component 511 drives the support component 530 to rotate counterclockwise to reset. The first drive component 511 drives the whole to return counterclockwise to the discharge end of the feeding conveyor 300. The disposal device 500 can dispose of garbage into the corresponding garbage bin 700 based on the information fed back by the camera 400. It adopts a wheel-type design with a short movement stroke, which improves the transfer speed. The cooperation between the insertion post 541 and the slot 514 makes it easy to disassemble and install, and facilitates later maintenance. When garbage falls from the feeding and conveying device 300 onto the support member 530, the second baffle 540 and the third baffle 550 can prevent the garbage from falling off the support member 530.

[0043] The remaining working principles of this embodiment are the same as those of Embodiment 2.

[0044] Another implementation of the disposal device 500 is provided here. In this implementation, four trash cans 700 are arranged in a straight line. The first driving member 511 is a cylinder. The first driving member 511 drives the support member 530 to move along the arrangement direction of the trash cans 700. The second driving member 521 is installed on the support member 530, and its output end is connected to the second baffle 540. During the transfer of trash, the first driving member 511 can drive the support member 530 and the second baffle 540 to reach the corresponding trash can 700. Then the second driving member 521 starts to push the trash into the corresponding trash can 700. However, compared with the above embodiment, this design has a longer stroke, requires more time to reset, and has a slower sorting speed.

[0045] Example 3

[0046] This embodiment is a third embodiment of a sorting device. This embodiment is similar to embodiment two, except that, as shown in the example... Figure 1As shown, the feed conveying device 300 is a belt conveyor mechanism. The conveying direction of the feed conveying device 300 is parallel to the horizontal plane and perpendicular to the conveying direction of the first conveying mechanism 210. Both sides of the feed conveying device 300 are provided with first baffles 310. In addition, the feed conveying device 300 can also be a chain conveying mechanism, a roller conveying mechanism, etc.

[0047] The working principle of this embodiment is as follows:

[0048] After the waste leaves the separating device 200, it falls onto the feeding conveyor 300 below. The feeding conveyor 300 moves the waste horizontally, and the camera 400 captures and identifies the images during this process. The entire conveying process is smooth. The waste piled together will move forward at different speeds after being separated by the separating device 200, and the time it takes to fall from the separating device 200 into the feeding conveyor 300 will also be different. The position of the waste falling on the feeding conveyor 300 will also be different, which improves the accuracy of detection. The second baffle 310 can block the waste and prevent it from leaving the feeding conveyor 300 due to its high speed.

[0049] The remaining working principles of this embodiment are the same as those of Embodiment 2.

[0050] Example 4

[0051] This embodiment is a fourth embodiment of a sorting device. This embodiment is similar to embodiment three, except that, as shown in the following... Figure 5 and Figure 6 As shown, the device also includes a compression device 600. A rectangular compression groove is provided on the side of the recyclable waste bin 700. The compression device 600 includes a third drive component 610 fixed to the frame 100 and a compression plate 620 connected to the output end of the third drive component 610. The third drive component 610 is a linear motor, and the compression plate 620 is slidably connected to the compression groove. A cover plate is provided outside the frame 100, and the cover plate and the frame 100 are fixed together by magnets. The third drive component 610 drives the compression plate 620 to slide within the compression groove, compressing the waste in the recyclable waste bin 700. Since recyclable waste includes aluminum cans, plastic bottles, etc., which take up considerable space and are easily compressed, the compression device increases the storage capacity of the waste bin 700. The cover plate seals the frame 100, reducing odor emissions.

[0052] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
